Shoot necrosis caused by <I>Phoma incompta</I>, a new disease of olive in Croatia

Abstract

Reddish-brown lesions on young shoots, withering of leaves, cankers on older shoots and shoot necrosis were observed on some olive trees in southern Croatia. The fungus Phoma incompta was identifed as the causal agent of the disease. Pathogenicity of P. incompta isolates was confrmed by inoculating young olive plants in a greenhouse; these plants developed symptoms similar to those observed in the field.
